In previous implementation Container service handlers didn't cache the
results of `Get` / `GetEACL` / `List` operations. As a consequence of this,
high load on the service caused neo-go client's connection errors. To avoid
this there is a need to use cache. Object service already uses `Get` and
`GetEACL` caches.
Implement cache of `List` results. Share already implemented cache of Object
service with the Container one. Provide new instance of read-only container
storage (defined as an interface)to morph executor's constructor on which
container service is based. Write operations remained unchanged.

In previous implementation wrapper over the Container contract's client

changes in API Go lib table carries its signature. Thus, it is redundant
to pass the eACL table signature separately.

Make `Get` method of the wrapper over Container contract's client to
accept binary container ID. Create `Get` function similar to the previous

where `Get` method was used.

Implement a component for transmitting the value of the used container space
along a route defined in the system. Implement WriterProvider interface on
it. By implementation, it is the link between the route planner and the
point-to-point transmitter, and abstracts from the implementation of both of
them. In the future, this implementation will be used as a transmitter of
local estimates of storage nodes among themselves.

Implement a component that stores the values of the used space of
containers. The storage allows you to write several values for a fixed
container and epoch number, and read the averaged estimates of all
accumulated values. All values are stored in memory. This component is
planned to be used as an accumulator of opinions from various network
participants about the fullness of the container.

Implement a component that connects the value stores of the used space of
containers. Implement the Start/Stop operations on it, which will later
become the application handlers of the corresponding events from the
sidechain. The main task of the controller is to temporarily synchronize the
stages of calculating the global estimate of the used space in the
container. The details of the score calculation (the way of collecting /
transmitting local scores, the final score formula and writing to the
contract) are encapsulated in the dependency components, the controller is
abstracted from them.
